Answer #1

The reactor has the efficiency of 24%. So, the energy required to generate 950 MW is

We know that the energy released by a nuclei in fission reaction is 200 MeV.

So, total number of nuclei required to produce 3958.33 MW of energy for 1 year is

Now mass of the uranium is

Burning 20 tons of coal provides about  joules, which is approximately the annual energy requirement of an average person in the United States. If this amount of energy was provided by the electricity generated by the fission of uranium-235 in a nuclear reactor, instead, what mass of natural uranium would be required? About 0.7% of natural uranium is uranium-235 (almost all the rest is uranium-238, which does not fission like U-235 does). Assume that the fission of each U-235 atom provides...
